What difference did Russia allegedly make?
Politicians are intent on putting spin, lying, putting out fake news, borderline slander and generally egging on the worst instincts of society in order to win.
When there is no interest in the truth or sensible cooperative discussion to sort out issues and they rely on bribes and promises they don't intend to keep to get into office.
Russia are no saints, but they've done this because the western political systems are so corrupt and broken now. Their own population is led around by fake news and slanted reports.
Or is only okay to carry on when it's the native government deceiving the people and not when a foreign power sticks it's oar in.
Basically, I think it wouldn't have happened, couldn't have happened had the politicians of the country in question had not sunk to the lowest in their desperate morally bankrupt race to get in at all costs.
